Cardiovascular outcomes trials (CVOTs) are a robust method to evaluate the safety of drugs, focusing on cardiovascular (CV) outcomes. CVOTs were advised by the US Food and Drug Administration (FDA) in 2008 for all new type 2 diabetes (T2D) treatments.1 In the LEADER trial, Victoza® met the primary objective of showing non-inferiority (no increased CV risk) vs placebo, both on top of standard of care, as well as demonstrating superiority with a statistically signi�cant reduction in cardiovascular risk.2
LEADER was a randomised, double-blind, placebo-controlled CVOT, undertaken to assess the long-term effects of liraglutide on CV outcomes and other clinically important events in adults with T2D and high CV risk.3
Selected secondary endpoints3
• First occurrence of an expanded composite CV outcome of CV death, non-fatal MI, non-fatal stroke, revascularisation, hospitalisation for unstable angina or hospitalisation for heart failure
• Serious adverse events and medical events of special interest
• Time from randomisation to all-cause death
• Time from randomisation to each individual component of the expanded composite CV outcome
• Time from randomisation to individual and composite microvascular outcomes (eye and kidney)
Primary endpoint3 • The time from randomisation to a composite outcome of the �rst occurrence of CV death, non-fatal myocardial infarction (MI), or non-fatal stroke. These endpoint de�nitions follow FDA guidance for major adverse cardiovascular events (MACE)
